It’s that time of year again! The weather is getting warmer, and you know what that means—it’s time to start thinking about your air conditioner. After all, you don’t want to be stuck in the sweltering heat with a broken AC unit. That’s why it’s crucial to ensure you know some essential tips for maintaining your AC system.

But what exactly does that entail? Never fear because we’re here to help. Read on for our top tips for keeping your AC system in tip-top shape.

Learn How Your Air Conditioner Work

It may seem like a no-brainer, but it’s essential to have a basic understanding of how your AC system works. That way, if something goes wrong, you’ll have a better idea of the issue.

Of course, you don’t need to know every detail about your AC unit. But it’s helpful to know the basics, like how the coolant system works or the main components. You can learn about this by reading your AC unit’s manual or doing a quick online search.

Usually, your air conditioner works when the refrigerant is often circulated through a system of coils and compressors to power your AC. As it goes through the evaporator coils in your home, the refrigerant absorbs heat from the air there before releasing it through the condenser coils. This process continues until the desired temperature is reached, at which point the AC unit will cycle off until the temperature inside your home rises again.

Change Your Filters Regularly

One of the most important things you can do to maintain your AC system is to change your filters regularly. Depending on your filter type, you should change it every one to three months. It may seem like a lot, but it’s important to remember that your AC unit has to work harder when the filter is dirty, which can lead to costly repairs down the road. Not sure how often to change your filter? Set a reminder on your phone or calendar, so you don’t forget.

Routinely Clean Your AC Unit

In addition to changing your filters, you should also regularly clean your AC unit. It means removing any leaves, dirt, or other debris that may have gathered around the unit. You should also clean the coils and fins on the unit itself.

One easy way to keep your AC unit clean is to invest in a cover. It will help protect it from the elements and make cleaning easier when necessary.

Know How to Repair Fins

The coils and fins on your AC unit can get bent or damaged over time. If this happens, it can cause your unit to work less efficiently, which means higher energy bills for you. That’s why it’s essential to know how to repair fins.

Fortunately, it’s not too difficult to do. You’ll just need a soft brush, a fin comb, and some patience. Use the brush to remove any dirt or debris from the fins. Then, use the fin comb to straighten out any bent fins.

Deal With Strange Noises ASAP

If your AC unit starts making strange noises, it’s essential to address the issue immediately. These noises could signify a serious problem. The sooner you deal with it, the better.

Some common AC noises include clicking, hissing, buzzing, rattling, or grinding. If you hear any of these, turn off your AC unit and call a professional for help.

Clean Your Vents and Coils

In addition to changing your filters, you should clean your vents and coils regularly. It helps improve airflow and prevents your unit from overworking itself. To clean your vents, simply remove them from the wall and vacuum them with a brush attachment.

As for the coils, they can be a bit more tricky. You’ll need to turn off your AC unit and remove the access panel before carefully cleaning them with a coil brush. Once you’re finished, ensure everything is back in its proper place before turning your unit back on.

Use a Programmable Thermostat

Investing in a programmable thermostat is a great way to save money and keep your AC unit running efficiently. With a programmable thermostat, you can set the temperature for when you’re home and away. You don’t have to waste energy cooling an empty house.

There are several different programmable thermostats on the market, so take your time to find one that best suits your needs.

Check for Air Leaks

Air leaks can cause your AC unit to work overtime, costing you more money in the long run. To prevent this, it’s essential to check for air leaks around your home and seal them up.

Common places for air leaks include doors, windows, and electrical outlets. To seal these leaks, simply use weather stripping or caulk.

Know Some Basic Troubleshooting

Even if you take all the necessary precautions, there’s always a chance that something could go wrong with your AC unit. That’s why it’s essential to know some basic troubleshooting tips.

If your AC unit isn’t working correctly, you should first check the thermostat to ensure it’s set to the correct temperature. You can try resetting the circuit breaker if that’s not the problem. If neither of these solutions works, you’ll need to call a professional for help.

Schedule Annual Maintenance Checks

Even if you’re diligent about changing your filters and cleaning your vents and coils, it’s still a good idea to have an annual maintenance check performed by a professional.

During these checks, the technician will thoroughly inspect your unit for any potential problems and make any necessary repairs or adjustments. They’ll also be able to clean areas difficult for you to reach on your own. While an annual maintenance check may seem unnecessary, it’s worth it in the long run as it can help extend the life of your AC unit.


Maintaining your AC system is vital to stay cool and comfortable inside your house. Following these simple tips can help ensure that your AC system runs efficiently. Don’t wait until there’s a problem to start thinking about maintenance—by then, it may be too late. So if you haven’t already, add these tasks to your spring cleaning list today. Your AC unit will thank you!
